Question

我有一个自定义方面我试图添加到我的服务中以自动记录所有错误并发出相应的错误消息，但是当我尝试将其应用于类并将Attributetargetelements设置为Multicast.method或将其应用于个人方法，我的服务返回500错误，错误消息

我有办法解决这个问题吗？

我的代码如下

服务方面

[Serializable]
public class ServiceAspect : OnMethodBoundaryAspect
{
    //create logger

    private static readonly log4net.ILog log = LogManager.GetLogger(typeof(BrokerServiceAspect).Name);//

    public override void OnException(MethodExecutionArgs args)
    {
        log.Error(args.Exception.Message, args.Exception);//log specific type of error
        args.FlowBehavior = FlowBehavior.Return;//return excution

        if (args.Exception is NullReferenceException)
        {
            args.ReturnValue = new FaultException(BrokerFaultCodes.NullExceptionCode);
        }
        else if (args.Exception is Exception)
        {
            args.ReturnValue = new FaultException(BrokerFaultCodes.GenericException);
        }
    }
}

并将其应用于班级

[ServiceAspect(AttributeTargetElements = MulticastTargets.Method)]
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, InstanceContextMode = InstanceContextMode.PerCall,IncludeExceptionDetailInFaults = true)]
public class APIService : ServiceBase,IAPIService
{

一旦从代码中删除服务方面，它就会按预期工作。

编辑

设置[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]以替换[Serializable属性现在返回

我已经考虑过了，但问题是由于ServiceAspect上的[Serializable]属性，服务无法启动。将serializable属性更改为[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]会返回 Method not found: 'Void API.Model.Infrastructure.Aspect.ServiceAspect.OnException(PostSharp.Aspects.MethodExecutionArgs

请查看此discussion。您的项目中可能有两个不同版本的PostSharp.dll。

Postsharp Methodboundry方面不适用于WCF服务类
